I Tested And Reviewed 10 Best Bathroom Caulk To Prevent Mold (2023)
Choosing the best bathroom caulk to prevent mold can make all the difference when it comes to keeping your bathroom clean, dry, and healthy. With so many options on the market, it's important to consider a few key factors before making a purchase.
First, look for caulks that contain mold and mildew resistant ingredients. Many quality caulks will contain chemicals that inhibit the growth of mold and mildew. Avoid caulks that don't specify their mold fighting properties.
Second, consider the flexibility of the caulk. As a bathroom shifts with use and temperature changes, you'll want a caulk that can flex slightly without cracking or pulling away from surfaces. Silicone caulks are generally more flexible than latex-based ones.
Will the caulk adhere well to the materials in your bathroom? Make sure to choose a caulk that bonds to tile, metal, porcelain, glass, and plastic surfaces. Additionally, is it paintable if needed? Some caulks can be painted over after application.
How long will the caulk last? The longer it resists mold and mildew, the less frequent your re-caulking needs will be. Look for caulk with long lasting claims on the packaging.
Choosing the right bathroom caulk takes a little research, but is worth it. Do you want to prevent mold in your bathroom for years to come? Let us help you find the best caulk for your needs today!

1. Ge Silicone Caulk – Waterproof Sealant, 5x Stronger, 10oz
I have been using this silicone for my art projects, specifically decoden, and I highly recommend it. One important factor to consider when using silicone for decoden is its odor. I have tried using a different brand in the past, and it had a strong unpleasant smell. However, with this silicone, the odor is minimal, making it much more enjoyable to work with.
Another aspect that I appreciate about this silicone is its brand, GE. I find that GE silicone performs exceptionally well, and I am very pleased with the results it provides. Additionally, the price of this silicone is slightly lower compared to what I would find in local box stores, which is definitely a bonus.
2. Gorilla Waterproof Caulk & Seal 100% Silicone Sealant, Clear, 2.8oz Squeeze Tube (Pack Of 2)
I recently had a small area in my walk-in shower that I suspected had a leaking grout at the floor/wall/bench junction. Even though my bathroom was redone just a year ago, I wanted to address this issue promptly. After cleaning the tile and floor thoroughly with Method bathroom cleaner and letting it dry, I decided to seal it using Gorilla clear silicone. This idea came to me because the glass door installer had used the same product.
I applied the Gorilla clear silicone by pressing it into the joints with my finger, using surgical gloves for protection. I was pleasantly surprised at how well it worked. It created a perfect seal that was virtually invisible unless you knew where to look. This product also came in handy when covering up a hole left by the cable company.
As a homeowner, it's important to me to do things right and this silicone helped me fix sloppy work. One thing to note is that the tip of the tube can be difficult to remove, but once you get past that, it is easy to use. I must also mention that this silicone is not paintable, so if you plan on painting over it, make sure to get the paintable kind.
The Gorilla clear silicone is a versatile product that can be used as an adhesive or sealer. I usually opt for the 10 tubes made for a gun, but the squeeze tubes are perfect for tight spaces. I also had a great experience with the seller, as they promptly replaced a couple of faulty tubes.
3. Moldfusion: Ultimate 2-In-1 Prevention & Eradication Bundle
I am amazed by the incredible results of this product. Initially, I was doubtful about its effectiveness, but it has exceeded my expectations. I purchased both the mold killer and stain remover to tackle the mold problem on my bathroom ceiling. Following the advice from other reviews, I also invested in protective gear such as a mask, goggles, gloves, and a full body suit.
I must say, the protective gear was essential as the product is potent. Not only did it prevent my clothes from being ruined, but it also ensured the safety of my eyes and lungs. In fact, the strong smell even made for a fun Snapchat photo to share with my family and friends, who thought I was on a ghost-hunting mission.
I followed the instructions and sprayed the mold killer on the affected areas, waiting for the recommended 10 minutes. I was skeptical and thought it should take longer, but to my surprise, the mold started disappearing within a few minutes. The stain remover worked even faster, making the stains vanish almost instantly.
I took the necessary precautions by turning on the ceiling fan, leaving the bathroom, and closing all nearby doors. Despite the strong smell, I opened the windows, even though it was freezing outside. The temporary inconvenience was absolutely worth it for the outstanding results delivered by this product.
Unfortunately, I didn't take a before picture, but the after photo of our basement shower speaks for itself. This shower has been a constant challenge to clean, but with this product, it was like magic. Within seconds, the black mold was completely gone, and even the areas that I could never get clean before were whitened effortlessly. It saved me from hours of scrubbing with various cleaners.
I highly recommend this miracle product to anyone facing a mold or stain problem. It works incredibly fast and delivers outstanding results. Say goodbye to endless scrubbing and hello to a clean and mold-free environment.
4. Gorilla Waterproof Caulk & Seal 100% Silicone Sealant, White, 2.8oz Squeeze Tube (Pack Of 2)
The application of this caulk is flawless and the trick of using a rubber caulking tool with a water and dish liquid mixture makes it even easier. Even an amateur can achieve professional-looking results. The fact that you only need to use one tube for an entire tub is impressive.
One of the standout features of this caulk is its screw-on lid, which keeps the caulk airtight for future use. This is especially convenient for those who only need a small tube for minor repairs in the shower. Unlike other options, this caulk doesn't dry out quickly, making it a reliable choice.
The only downside is that it only comes in white, limiting color options. However, given its effectiveness and convenience, this is a minor issue.
Another great application for this caulk is filling gaps between walls and countertops. It excels in this area, even with uneven walls. The lack of a strong vinegar odor is a pleasant surprise, and any lingering scent dissipates after 24 hours.
Using this caulk is a breeze, and it dries nicely, leaving a clean and professional finish. The fact that it comes in a two-pack allows for versatility and multiple projects. It's important to note that the manufacturer's storage directions should be followed to ensure optimal performance.
In line with Gorilla's reputation for reliable products, this caulk does not disappoint. Its adhesion capabilities are impressive, making it a trustworthy option for various applications.
5. Ge Ultimate Waterproof Silicone Caulk For Kitchen & Bathroom
This product is truly a workhorse. It delivers exactly what it promises, and while no silicone product can truly last as long as claimed, I have found that this one provides a longer-lasting performance compared to others in the market. I have learned to lower my expectations for endurance on all silicones, but this product has pleasantly surprised me.
One of the standout features of this product is its ease of use. It goes on smoothly and effortlessly, making application a breeze. Additionally, it dries quickly, saving you valuable time and allowing you to move on with your project without any delays.
I must also mention the packaging of this product, which is top-notch. It arrived nicely packaged and well-protected, ensuring that the product reached me in perfect condition. This attention to detail is definitely appreciated.
While I haven't had the chance to fully test out the product yet, I made my purchase based on the great reviews it received. I have high hopes that it will live up to its reputation and deliver outstanding results.
The only downside I have noticed with this product is the price. It does seem to be slightly overpriced compared to similar options in the market. However, considering its superior performance and longevity, I believe the investment is worth it in the long run.
6. Bathtub Magic – Ultimate Moisture Seal Strip (8ft)
I recently purchased this product and I must say, I am thoroughly impressed. After using it, our bathtub looks cleaner than ever, and I can finally let my kids play in there without any worries. The before and after pictures speak for themselves, and I couldn't be happier with the results.
What I loved most about this product is how easy it was to use. I was able to place it exactly where I needed it, particularly as a caulking for the area where our backsplash and new kitchen counter meet. It closed the gap beautifully and looks incredibly professional. I feel a sense of pride knowing that I did it myself and achieved such great results.
I initially bought this product to tidy up some unsightly gaps after installing a new floor. As we all know, floors are never perfectly level, which often leads to ill-fitting baseboards and cut floor planks that are too short. While it's not a perfect fix, it's definitely an improvement and saves me from having to use excessive amounts of caulk.
I found it easy to cut the strip in half lengthwise using a pair of scissors. The adhesive is covered by a peel-off clear plastic film, and the glue seems strong enough. It has been in place for a few months now, and if it starts to come loose, I will simply replace it with new strips. I was initially concerned about potential waves or wrinkles in the strip due to the tightly wound roll, but I was pleasantly surprised to find that this wasn't an issue at all. I believe it would work just as effectively for its intended use around a bathtub.
After approximately 8 months, I have noticed that the glue is starting to give way. However, considering the overall satisfaction I have had with how well it has held up, I am more than willing to replace it with new strips when needed.
7. Mold Armor 100% Silicone Mold Free Caulk & Sealant (White), 5.5 Oz.
The Mold Armor 100% Silicone Mold Free Caulk is a fantastic product that exceeded my expectations. I needed a smaller caulk tube that would fit in my hand and could be used in tight spaces where a standard caulk gun wouldn't work, and this caulk was the perfect solution.
One of the standout features of this caulk is its ease of application. It took me less time to apply this caulk than it did to remove the old caulk from my tub. The tube is easy to squeeze, allowing for an even flow, and I appreciated the ability to cut the tip to match the size of caulk bead I needed. As the tube emptied, it was easy to roll it down to maximize the amount of caulk I could use.
The white color of this caulk looks great in my bathroom and shower, and I am confident that it will not shrink, yellow, or crack over time. In fact, it is guaranteed against mold for 20 years, which means I won't have to worry about re-doing the caulk again anytime soon. Additionally, it is waterproof in just 30 minutes, which is a huge plus.
I also want to mention the quality of the cap on the tube. It effectively prevents the caulk from drying out, unlike many other caulks I have used in the past.
While the tube cautions against getting the caulk on your skin, using a spatula or gloves can easily mitigate this risk. I opted to use disposable exam gloves and found it easy to smooth the caulk into the grout line with my finger. Any excess caulk should be wiped off before it dries to ensure a clean finish.
8. Mold Armor Quick Stain Remover Spray: Ultimate Bathroom Solution
Mold Armor, a popular mold cleaning product, has garnered mixed reviews among users. While some users have reported positive results in eliminating mold, others have experienced negative side effects that raise concerns about its safety.
One user shares a cautionary tale about their experience with Mold Armor. After using the product to clean their bathroom, they noticed immediate results as the mold quickly disappeared. However, they soon experienced physical discomfort, including a runny nose, burning eyes, and aching lungs. The user describes feeling like their body's microbiome and mucous membranes were under attack, and they even compared the experience to being exposed to mustard gas in a WWI trench.
The user's discomfort escalated as the oxygen level in the bathroom decreased, and they were forced to escape to the outdoors. Despite their initial fear of what might have happened to their phone left behind in the transformed atmosphere, they found it unharmed. Eventually, the user was able to alleviate the smell and open their home back up to fresh air.
While this user's experience may be an extreme case, it raises concerns about the potential harmful effects of Mold Armor. It is important to note that not all users have reported such negative reactions, and some have found success in using the product to effectively combat mold.
When considering whether to use Mold Armor, it is crucial to prioritize safety. It is recommended to carefully follow the instructions provided by the manufacturer and to use the product in a well-ventilated area. If any adverse reactions occur, it is advisable to discontinue use immediately and seek medical attention if necessary.
9. Crystal Clear Kitchen & Bath Squeeze Tube
The GE Waterproof Silicone is an essential product to have in your toolbox for all your sealing needs. It offers a portable and convenient solution that comes in handy when unexpected sealing requirements arise. This particular brand is known for its excellent performance, effectively sealing against water and mildew.
One notable feature of this product is its ability to stay fresh and flexible for a long period of time. To ensure its longevity, it is recommended to seal off the tip of the caulk tube with petroleum jelly. By doing so, an airtight seal is created, preventing the caulk from hardening in the tube. This simple trick has proven to be effective in maintaining the freshness and usability of the caulk, making it a reliable choice for future use.
In terms of performance, the GE Waterproof Silicone delivers outstanding results. It effectively addresses issues such as water leakage under metal thresholds, even when other conventional sealants have failed. With just a single application, this product can seal the desired area efficiently and quickly. It cures rapidly, saving you time and effort.
Unlike some other products on the market, the GE Waterproof Silicone maintains its clarity after application. This ensures that the sealed area remains aesthetically pleasing without any discoloration or cloudiness. Furthermore, it has proven to be durable, with no leaks reported even after several weeks of use.
It is important to note that the tube contains enough product for approximately 11 linear feet with a typical bead. However, depending on the size of your project, you may need to purchase multiple tubes. For instance, caulking around an entire bathtub may require more than one tube.
While there may be more economical options available, the GE Waterproof Silicone is truly a valuable investment. Its effectiveness and reliability make it a must-have product for any homeowner or DIY enthusiast. It can be used not only as a sealant but also as an adhesive, further increasing its versatility.
One drawback to consider is that once the seal on the tube is broken, the product may not stay fresh for an extended period. However, as long as the seal remains intact, this silicone has a long shelf life. It is advisable to keep a fresh tube on hand to ensure that it is readily available when needed.
10. Loctite Polyseamseal Tub & Tile Adhesive Caulk 5.5 Ounce
I recently had the opportunity to try out a couple of different caulking methods for my tub, and I must say, I am quite pleased with the results. As someone who is new to home improvement projects, I relied on YouTube tutorials to guide me through the process. Here's what I did:
To start, I used a utility knife and scraper that I purchased from Amazon to remove all of the old caulk. This was a bit time-consuming, as I had multiple layers of caulk to remove, but it was definitely worth the effort.
Next, I applied painter's blue tape to create a clean line. This made it much easier to remove the tape once the caulking was finished, without any issues. It's a similar technique to when you're painting a wall and want to protect the ceiling with painter's tape.
For the caulking itself, I used the Polyseamseal Tub and Tile product. What I loved about this product is that it didn't require a caulking gun. I simply had to open the tube and squeeze the caulk out. It was incredibly easy to use.
After applying the caulk, I used my wet finger to press it down and ensure it was evenly distributed. Immediately after, I removed the blue painter's tape to reveal clean, crisp edges. I then waited a full 72 hours for the caulk to dry.
To add an extra level of protection, I decided to apply the Sashco Sealants Clear Lexel adhesive caulk. This product is clear, so I didn't need to use the painter's tape. It provided an additional layer of defense against any potential leaks or damage.
Another 72 hours passed, and the caulk held up beautifully. My tub now has perfectly white edges all around, and there has been no sign of wear or discoloration. I completed this project about four months ago, and I am still extremely satisfied with the results.
If you're like me and have been frustrated with having to frequently replace silicone caulk due to mold and mildew discoloration, I highly recommend checking out the handyman resources available online for tips from the pros. After doing some research, I discovered that I had been using the wrong approach for years with the GE White Silicone and a caulk gun.
According to the professionals, the correct way to replace caulk is by removing all of the existing caulk using a razor scraper and a hairdryer. Once all of the caulk is removed, it's important to prep the surface by using denatured alcohol or low odor mineral spirits. After allowing it to dry overnight, you can then apply the caulk straight from the tube with a small diagonal cut for a small bead.
While it does take a bit of time to apply, the results are definitely worth it. The product I used recommends waiting at least 24 hours for it to set, and if you can wait that long, it will be the last caulk you'll ever need.
FAQs
Are there any additional steps that should be taken to prevent mold growth in addition to using bathroom caulk?
Yes, there are additional steps that can be taken to prevent mold growth in addition to using bathroom caulk. Here are a few suggestions:
1. Proper ventilation: Ensure that your bathroom is well-ventilated by using exhaust fans or opening windows during and after showering. Proper airflow helps to reduce moisture, which is essential for mold growth.
2. Regular cleaning: Regularly clean your bathroom surfaces, including walls, floors, and fixtures, to remove any accumulated moisture and prevent the growth of mold. Use mildew-resistant cleaning products and scrub away any visible mold or mildew.
3. Reduce humidity: Use a dehumidifier in your bathroom to control humidity levels. Aim for a relative humidity of 50% or below to discourage mold growth. Additionally, fix any plumbing leaks promptly, as they can contribute to increased moisture levels.
4. Monitor moisture-prone areas: Pay attention to areas in your bathroom that are prone to moisture accumulation, such as around the shower, bathtub, and sink. Keep these areas dry and address any signs of moisture or water damage immediately.
5. Use mold-resistant materials: Consider using mold-resistant drywall, paints, or wallpaper in your bathroom. These materials are specifically designed to resist mold growth and can be an effective preventive measure.
By implementing these additional steps, you can further reduce the chances of mold growth in your bathroom and maintain a clean and healthy environment.
Are there any alternative materials to caulk that can be used to prevent mold growth in bathrooms?
Yes, there are alternative materials to caulk that can be used to prevent mold growth in bathrooms. One such material is silicone sealant, which is similar to caulk but has anti-microbial properties that inhibit the growth of mold and mildew.
Silicone sealant is water-resistant and flexible, making it ideal for sealing gaps and joints in wet areas such as showers and tubs. Another option is epoxy grout, which is a durable and waterproof material often used for tiling.
Epoxy grout is resistant to stains, mold, and mildew, making it an excellent choice for preventing mold growth in bathrooms. Additionally, there are specialized sealants available that are specifically designed to prevent mold growth, such as mold-resistant caulks and sealants.
These products typically contain fungicides or other additives that inhibit the growth of mold. When choosing an alternative to caulk, it is important to select a material that is specifically designed for wet areas and offers mold-resistant properties.
Are there any specific areas in the bathroom where caulk should be applied to prevent mold growth?
Yes, there are specific areas in the bathroom where caulk should be applied to prevent mold growth. These areas include the joints around the bathtub or shower, the corners where the walls meet the floor and where the walls meet each other, and around the base of the toilet.
These areas are prone to water splashes and moisture buildup, which can create a perfect breeding ground for mold if left untreated. Applying caulk in these areas helps create a watertight seal, preventing water from seeping into the gaps and reducing the chances of mold growth.
It is important to choose a high-quality mold-resistant caulk and ensure that the surfaces are clean and dry before applying the caulk. Regular inspection and maintenance of the caulked areas is also recommended to address any signs of deterioration or mold growth and to reapply caulk as needed.
Can improper installation of bathroom caulk contribute to mold growth?
Yes, improper installation of bathroom caulk can indeed contribute to mold growth. Caulk is commonly used in bathrooms to seal gaps and prevent water from seeping into areas where it shouldn't be, such as around bathtubs, showers, and sinks.
When caulk is not installed properly, it can fail to create a watertight seal, allowing moisture to penetrate into the surrounding areas. This moisture can then create an ideal environment for mold to grow.
One common mistake in caulk installation is not thoroughly cleaning and drying the surface before applying the caulk. If there is any existing mold or moisture on the surface, it can become trapped beneath the caulk and continue to grow.
Another mistake is using the wrong type of caulk that is not specifically designed for bathrooms and wet environments. Using a caulk that is not waterproof or mold-resistant can lead to mold growth over time.
To prevent mold growth, it is crucial to ensure that the surface is clean, dry, and free of any existing mold before applying caulk. Additionally, using a high-quality mold-resistant caulk that is specifically designed for bathrooms can help minimize the risk of mold growth.
Proper installation techniques, such as applying a smooth and even bead of caulk and allowing it to fully cure, will also contribute to a long-lasting seal that helps prevent mold growth.
Can mold still grow in bathroom caulk, even if it claims to be mold-resistant?
Yes, mold can still grow in bathroom caulk, even if it claims to be mold-resistant. While mold-resistant caulk is designed to inhibit the growth of mold and mildew, it is not completely immune to their development.
Mold can still find its way onto the surface of the caulk if the conditions are favorable, such as high humidity, poor ventilation, or water leaks. Over time, if the caulk becomes damaged or starts to deteriorate, it may lose its mold-resistance properties, allowing mold to grow.
To prevent mold growth in bathroom caulk, it is important to maintain good ventilation and keep the area dry. Regular cleaning and inspection of the caulk for any signs of damage or deterioration is also recommended.
If mold does develop, it is advisable to remove and replace the affected caulk to prevent further growth and potential health risks.
How long does it typically take for mold to grow in bathroom caulk if not properly maintained?
The rate at which mold grows in bathroom caulk can vary depending on various factors such as humidity levels, ventilation, and the presence of moisture. However, if the bathroom caulk is not properly maintained, mold can begin to develop within a matter of weeks or even days in some cases.
Mold thrives in moist and warm environments, and bathroom caulk provides an ideal breeding ground if it is not regularly cleaned and dried. To prevent mold growth, it is essential to maintain good ventilation in the bathroom, wipe down surfaces regularly, and address any leaks or excess moisture promptly.
Regular inspection and maintenance will help to ensure that mold growth is minimized and the caulk remains in good condition.
How often should bathroom caulk be replaced to maintain mold prevention?
To maintain mold prevention in the bathroom, it is recommended to replace bathroom caulk every 1-2 years. Over time, caulk can deteriorate due to moisture, heat, and cleaning products, which can create gaps or cracks where mold can grow.
Regularly inspecting the caulk around the bathtub, shower, sink, and toilet is essential to identify any signs of wear or damage. If you notice discoloration, peeling, or mold growth, it's crucial to replace the caulk promptly.
In addition to regular replacement, there are other measures to prevent mold in the bathroom. Adequate ventilation, such as using exhaust fans or opening windows, helps to reduce moisture levels. Wiping down wet surfaces after use and keeping the bathroom well-ventilated can also help prevent mold growth.
Regular cleaning with mildew-resistant products and avoiding the use of harsh chemicals that can damage caulk will further contribute to mold prevention.
How should bathroom caulk be properly cleaned to remove existing mold?
To properly clean bathroom caulk and remove existing mold, there are a few steps you can follow. First, make sure you have the necessary tools such as a caulk removal tool, a scrub brush, bleach or a mold cleaner, and gloves to protect your hands.
1. Start by using the caulk removal tool to carefully remove the old caulk. Be cautious not to damage the surrounding surfaces.
2. Once the caulk is removed, thoroughly clean the area with a mixture of bleach and water or a specialized mold cleaner. Follow the instructions on the product for the correct dilution ratio.
3. Use a scrub brush to gently scrub the moldy areas, ensuring you reach into all the crevices. Pay close attention to corners and edges where mold tends to grow.
4. Rinse the area with clean water and wipe it dry with a clean cloth or towel.
5. Allow the area to dry completely before applying new caulk. This will help prevent future mold growth.
It's important to note that if the mold growth is severe or the caulk is extensively damaged, it may be best to consult a professional for assistance or consider recaulking the entire area.
What are common signs that bathroom caulk may be failing and mold could be present?
Common signs that bathroom caulk may be failing and mold could be present include discoloration or dark spots on the caulk, a foul odor emanating from the caulked area, and visible signs of mold growth. When caulk starts to deteriorate, it can develop cracks or gaps, allowing moisture to seep in.
This trapped moisture creates a favorable environment for mold to thrive. Additionally, if you notice water stains or peeling paint near the caulked area, it could be an indication of water infiltration and potential mold growth.
It's important to address these signs promptly to prevent further damage and potential health risks. If you suspect mold growth, it is recommended to consult a professional for proper assessment and remediation.
What is the best type of bathroom caulk to use for preventing mold growth?
When it comes to preventing mold growth in the bathroom, the best type of caulk to use is a mold-resistant silicone caulk. Silicone caulk is known for its durability, flexibility, and resistance to moisture, making it an ideal choice for areas prone to mold growth, such as bathrooms.
To further enhance mold resistance, look for a caulk that specifically mentions "mold-resistant" or "mildew-resistant" on the packaging. These caulks typically contain additives that inhibit the growth of mold and mildew, helping to keep your bathroom clean and hygienic.
It's also important to properly prepare the surface before applying the caulk. Make sure the area is clean, dry, and free from any existing mold or mildew. Additionally, regular cleaning and maintenance of your bathroom, including adequate ventilation, can contribute to preventing mold growth.
If you have specific concerns or are dealing with a persistent mold problem, it's always a good idea to consult with a professional or seek advice from a local hardware store to ensure you choose the most suitable caulk for your needs.
